Moreover, any

conventional heating means, such as the electric heating'element 11, connected to the electric leads 15, may be positioned under the sealing tables 10, as shown more par- 20 ticnlarly in Figs. 7 and 8. Although this construction, except in that it enters into the combination with my invention, is entirely conventional, the provision of a heater is immaterial. ,thatfeature being common 5 with existing bread wrapping machines.

The operation of my invention should now be clear. As seen in F i 7. as the wrapped articles or bread are moved forwardly by the conveyors 9 and 2, with the ends of the 30 wrapped paper unsealed, the tables rise and fall, the base in their raised posit-ion effect ively sealing said ends together as the bread or articles are conveyed thereover. As the articles reach the tables 10, the fingers 7 35 push said articles under the pressure shoe 6, r

the sealing being accomplished as just described.

\Vhile I have thus described my invention with great particularity, it will be clear that 40 the same may be modified throughout a wide range. I accordingly do not propose to be limited to the exact details of construction shown and described, but'r'eserve the right in practice to make any and all modifications 45 thereof that fall within the scope of the ap- 1 10 pended claims.

I claim as my invention: 1. A sealing table adapted for special use in connection with an article wrapping maso-ehine, comprising a flat base, a hinge por- 11:

tion on one end of said base, an extension depending upon said hinge portion. a downwardly bent pin engaging portion, and spring means associated with said extension 3.) and said pin for causing said downwardly bent portion to be raised and lowered on said pin.

2. A sealing table comprising a sealing base, a bifurcated downwardly bent joint '0 portion on one end of said base, a pair of 12 downwardly curved portions on the other I end of said base, and an extension depending from said base and positioned between said downwardly curved portions.

3. A sealing table for use in connection 11
